When I lived in Scotland, every householder had a T-shaped key to turn off the water at the stopcock in the street. The stopcock consisted of a tapered tap and a half-turn of the key shut it off.
When I moved to England, I was told it was a criminal offence for a householder to turn off his own water supply in the street and only servants of the water company were allowed to this and the water company charged vast fees for doing it.
Can someone please tell me the position as I want to replace the washer on the indoor stopcock under the sink?
